Osg 8710810 Taper Length Drill Bit 0.3189 in Solid Carbide

Product Description

The OSG 8710810 is a taper length, solid carbide drill bit designed for precision hole-making in demanding machining applications. Built to Series 6530 standards, it features a 140-degree split point with X-thinned web geometry that reduces entry force and improves centering without a pilot hole. The EgiAs finish supports heat resistance and surface durability during high-speed drilling. At 0.3189 inches (8.10 mm) in diameter with a 10xD flute-to-diameter ratio, this bit is suited for deep-hole drilling where rigidity and chip evacuation are critical. Coolant-through construction allows internal fluid delivery directly to the cutting zone, extending tool life in ferrous and hard-material applications.

This drill bit is intended for use in CNC machining centers and drill presses in industrial and precision manufacturing environments. The straight shank with a 10.00 mm shank diameter seats securely in standard collet chucks and drill chucks of appropriate size. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. The taper length body provides greater reach than jobber-length bits while maintaining stiffness. Machinists, tool-and-die makers, and precision fabricators working with tight-tolerance bore requirements will find this geometry well suited to their setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree split point with X-thinned web reduces walking and entry force
• EgiAs finish enhances heat and wear resistance at the cutting edge
• Coolant-through design delivers fluid directly to the cutting zone
• 10xD flute length-to-diameter ratio supports deep-hole applications
• Right-hand spiral flutes for efficient chip evacuation

Compatibility

Designed as an OEM-style taper length drill bit for use in CNC machining centers and drill presses accepting a straight shank with a 10.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and power is locked out before loading or changing the bit. Secure the straight shank fully within the collet or chuck to the recommended engagement depth per the toolholder manufacturer. When using the coolant-through feature, verify that the machine coolant system is compatible and that through-spindle pressure is set per the machining center specifications.
